This comprehensive guide to non-toxic workout clothes is perfect for fitness enthusiasts looking to create a healthier, more sustainable activewear collection.
When I was younger I never gave much thought to the clothes I wore to the gym. I’d throw on an old t-shirt, and a pair of leggings, lace up my sneakers and I was ready to sweat.
As long as my clothes were comfortable and I could move easily, I didn’t think it mattered what they were made of. Boy was I wrong.
In recent years, I’ve learned that toxic chemicals are hiding almost everywhere– in our cookware, makeup, and even our yoga mats. So when I discovered that toxic chemicals are also in our workout clothes, I can’t say I was too surprised.
What did surprise me, however, was just how easily these chemicals can enter our bodies when we exercise. The combination of sweat, friction, and body heat actually accelerates the migration of chemicals from clothing into our skin.
And if our workout clothes happen to be made with toxic chemicals like PFAS, phthalates, and formaldehyde (spoiler alert: a lot of them are!), those chemicals are making their way into our bodies with every burpee and bicep curl.
So just like eating healthy and getting enough sleep, non-toxic workout clothes are an equally important piece to staying healthy. So I’ve made it my mission to find the best non-toxic workout clothes out there.
Ones that not only perform well and look great but are also looking out for our health by using organic, natural materials as much as possible.
In this article, I’ll be doing a deep dive into the problematic chemicals and materials found in most workout wear brands and sharing my top picks for the best non-toxic workout clothing brands that will have you looking and feeling your best during every workout.
The Problem with Conventional Workout Clothes
PFAS: The Toxic “Forever Chemicals” in Your Workout Clothes
The most concerning chemicals found in workout clothes are PFAS, or per- and poly-fluoroalkyl substances.
Recent lab testing has revealed a scary fact: a whopping 25% of workout leggings, yoga pants, and leisure leggings contain detectable levels of PFAS.
Workout wear brands rely on these “forever chemicals” to make their clothing moisture-wicking and stain-resistant.
Even more concerning, the highest concentrations were often discovered in the crotch area of the leggings, with levels reaching as much as 284 ppm (parts per million) of organic fluorine, an indicator of PFAS presence.
While there is no established safe level of PFAS in clothing, any presence is generally considered unsafe due to PFAS’ serious health impacts, including:
- Reduced immunity, makes you more susceptible to illness and infection.
- Metabolic diseases like obesity and diabetes, throw your body’s delicate balance into disarray.
- Cardiovascular issues put extra strain on your heart and blood vessels.
- Fertility problems make it harder to conceive or maintain a healthy pregnancy.
- Increased cancer risks, particularly in the kidneys and testicles.
- Hormonal disruption wreaks havoc on your body’s natural rhythms and functions.
It’s a toxic domino effect that can have far-reaching consequences for your overall health. And the worst part? These risks are not always immediately apparent.
PFAS can accumulate in your body over time, silently building up with each workout until they reach levels that can no longer be ignored.
But PFAS Aren’t the Only Problematic Chemicals in Your Workout Wear
Now, you might be thinking, “I’ll just switch to activewear that’s labeled ‘PFAS-free’ and all will be fine.” If only it were that simple.
The truth is, even brands that claim to be PFAS-free may not be telling the whole story. There are many other problematic (toxic) materials used to make workout clothes, including:
- Phthalates: Used as plasticizers in polyester and nylon fabrics, phthalates can cause skin irritation and have been linked to allergies and endocrine system disruptions.
- Formaldehyde: Used as a finishing agent in nylon and chemically processed bamboo fabrics, formaldehyde is a known carcinogen and can cause skin irritation and respiratory issues.
- BPA (Bisphenol A): Found in some polyester-based fabrics containing spandex, BPA is a known endocrine disruptor linked to various health issues.
- Flame Retardants: Added to some workout wear to reduce fire risk, flame retardants can be harmful if absorbed through the skin, potentially causing neurological damage and other health issues.
- Heavy Metals: Contaminants like lead, mercury, and cadmium can cause skin irritation and, if absorbed, lead to severe health problems.
- Pesticide Residues: Found in workout wear made from treated natural fibers, pesticide residues can cause skin irritation and may lead to systemic health issues.
The Sweat Factor That Compounds Chemical Absorption
As if the presence of toxic chemicals in workout clothes wasn’t bad enough, there’s another factor that makes this toxic problem even worse.
As you sweat, your body becomes even more susceptible to absorbing these harmful substances through a mechanism known as “lipophilicity.” In simple terms, lipophilicity means that certain chemicals are attracted to the oils in your sweat like magnets.
As you exercise, these chemicals can leach out of your workout clothes and be absorbed directly into your skin, entering your bloodstream more easily than when you’re just lounging around.
This snug fit of workout clothes, combined with the extended periods of direct skin contact during exercise, creates the perfect storm for chemical absorption.
But don’t despair just yet! There are lots of great non-toxic workout clothes made from natural materials. Let’s dive into what to look for when shopping for safe, non-toxic workout clothes.
Best Natural Materials To Look For in Non-Toxic Workout Clothes
- Organic Cotton: When it comes to workout wear, look for GOTS (Global Organic Textile Standard) certified cotton. Organic cotton is incredibly breathable, and with the right blending techniques, organic cotton can provide the perfect balance of softness, stretch, and support for all your workout classes.
- Bamboo: Known for its sustainable and antibacterial properties, bamboo fabric acts as a built-in freshness shield, preventing the growth of odor-causing bacteria and keeping you smelling fresh even after intense workouts. Just keep in mind, when it comes to bamboo fabric, it’s important to distinguish between mechanically processed bamboo and chemically processed bamboo viscose.
- Hemp: This eco-friendly fabric is incredibly durable and resistant to UV rays, making it ideal for outdoor activities. It withstands rigorous workouts and frequent washing, while also being a sustainable choice for activewear.
- Merino Wool: Sourced from sheep, merino wool is a moisture-wicking fabric that naturally pulls sweat away from your skin, keeping you dry and comfortable. It is also naturally odor-resistant, reducing post-workout odors.
An Important Note About Our Non-Toxic Workout Clothes Recommendations
At TFC, we generally don’t like to recommend synthetic materials since synthetic fibers are often treated with toxic chemicals and the health risks associated with long-term exposure are still being studied.
However, when it comes to workout clothes, the use of a small percentage of these synthetic fibers is often unavoidable.
For our recommendations, we sought out non-toxic workout clothes that contained over 90% organic, natural materials like cotton, hemp, and wool.
When shopping for non-toxic workout clothes, look at the specific material percentages listed on each garment, since these can vary significantly between different items from the same brand.
Aim for products with a high percentage of organic materials and minimal synthetic content. So with that in mind, let’s get into our favorite non-toxic workout clothes!
Whether you’re concerned about harmful chemicals absorbing into your skin during sweaty workouts, reducing your environmental impact, or investing in high-quality pieces that perform without toxins, these carefully selected brands offer safer alternatives to conventional workout wear made with synthetic materials and chemical treatments like PFAS, phthalates, and toxic dyes.

Red Flags When Shopping for Workout Clothes
Marketing Claims to Question
- “Buttery Soft” Synthetic Fabrics: While the promise of ultra-soft, silky smooth fabric might be tempting, be wary of any synthetic materials described as “buttery soft.” This often indicates the presence of chemical additives and treatments that can irritate your skin and disrupt your hormonal balance.
- “Moisture-Wicking” Without Explanation: Many brands tout their fabrics’ moisture-wicking properties, but it’s crucial to understand how this effect is achieved. If a brand doesn’t specify the use of natural fibers or non-toxic treatments, there’s a good chance that PFAS or other harmful chemicals are involved.
- “Stain-Resistant” or “Water-Repellent”: While the idea of activewear that resists sweat stains and repels water might sound appealing, these properties often come at a cost. Stain-resistant and water-repellent treatments frequently rely on PFAS or other toxic chemicals that can leach into your skin and cause long-term health issues.
- Proprietary Fabrics: Some brands may boast about their innovative, proprietary fabric blends or technologies without disclosing the specific materials or treatments used. If a company isn’t transparent about what goes into their fabrics, it’s best to approach with caution and seek out brands that prioritize openness and honesty.
Problematic Product Features
- Strong Chemical Smells: If your new activewear has a strong, persistent chemical odor, even after washing, it’s a red flag that toxic chemicals are probably present. Natural, non-toxic fabrics should have a neutral or minimal scent, without the overpowering smell of chemicals.
- Unusually Low Prices: If a brand offers activewear with advanced performance features like moisture-wicking, stain resistance, or anti-odor properties at surprisingly low prices, it’s worth questioning how they achieve these effects. More often than not, budget-friendly options rely on cheaper, toxic chemicals to deliver these benefits.
- Missing or Vague Material Composition: Always check the label for a clear breakdown of the materials used in your activewear. If a brand is vague about the fabric composition, using generic terms like “stretch fabric” or “performance blend” without specifying the exact materials, it’s a sign that they may be hiding something.
Greenwashing Warning Signs
- Unsubstantiated “Eco-Friendly” Claims: If a brand proclaims its products to be “eco-friendly,” “sustainable,” or “non-toxic” without providing any evidence or explanation, it’s a red flag. Look for brands that back up their environmental claims with specific details about their materials, production processes, and third-party certifications.
- Lack of Specific Certifications: Reputable eco-friendly brands will often carry certifications from respected organizations like GOTS (Global Organic Textile Standard), OEKO-TEX, or Bluesign. If a brand claims to be sustainable but doesn’t have any recognized certifications, it’s worth questioning their commitment to genuine eco-friendliness.
- Vague Terms Like “Natural” or “Green”: Beware of brands that use vague, unregulated terms like “natural,” “green,” or “environmentally friendly” without providing any context or explanation. These terms can be misleading, as they don’t necessarily mean that a product is free from harmful chemicals or that it’s produced in an eco-conscious manner.
Care Instructions for Your Non-Toxic Workout Clothes
- Wash in Cold Water: Cold water is gentler on the natural fibers, preventing shrinkage and maintaining the shape and integrity of your activewear. Plus, washing in cold water saves energy and reduces your carbon footprint – a win-win for you and the planet!
- Use Mild, Non-Toxic Laundry Detergent: Look for non-toxic laundry detergents that are specifically formulated for delicate or activewear fabrics, as these will be gentler on your clothes and less likely to leave behind any residue that could irritate your skin.
- Avoid Fabric Softeners: While it might be tempting to use fabric softeners to give your activewear that extra softness and fresh scent, it’s best to avoid them altogether. Fabric softeners can leave a waxy residue on your clothes that can actually trap odors and bacteria. Plus, many fabric softeners contain harmful chemicals that can irritate your skin and disrupt your hormonal balance.
- Air Dry When Possible: The heat and tumbling action of a dryer can be tough on natural fibers, leading to shrinkage, stretching, and damage over time. If you do need to use a dryer, choose a low heat setting and remove your activewear promptly to minimize exposure to heat.
While these general care instructions will work well for most non-toxic activewear, it’s always a good idea to double-check the care labels on your specific clothes.
Some fabrics may have special requirements or recommendations, such as laying flat to dry or washing inside out.
Tips for Transitioning to Non-Toxic Activewear
Transitioning to a non-toxic activewear wardrobe doesn’t have to happen overnight. Here are some tips for getting started. You’ll be well on your way to a healthier, more sustainable workout wardrobe in no time.
1. Start with Your Most-Worn Items First
Begin your non-toxic activewear journey by focusing on the pieces you wear the most often. For many of us, that means leggings, sports bras, and go-to workout tops.
By replacing these high-rotation items first, you’ll make the biggest impact on reducing your exposure to harmful chemicals and enjoying the benefits of natural, organic fabrics.
2. Look for Sales and Discounts
We get it – non-toxic activewear can come with a higher price tag than conventional options. But that doesn’t mean you have to blow your entire workout budget on one pair of organic cotton leggings.
Keep an eye out for sales, discounts, and promotions from your favorite eco-friendly activewear brands.
Sign up for their newsletters, follow them on social media, and take advantage of end-of-season sales to snag some great deals on high-quality, non-toxic pieces.
3. Build a Capsule Workout Wardrobe
Rather than trying to replace every single piece of activewear you own at once, focus on building a versatile, mix-and-match capsule wardrobe.
Invest in a few high-quality, non-toxic staples in neutral colors that you can easily pair with each other. This way, you’ll have a range of outfit options without needing a closet full of clothes.
This has been your guide to the best non-toxic workout clothes for 2025.
Just like being mindful of what we put in our bodies, being conscious of what we put on our bodies during workouts is a game-changer for our health.
The good news? You don’t have to sacrifice style or performance to avoid toxic chemicals with these awesome non-toxic workout clothes.
Remember, transitioning to a cleaner workout wardrobe doesn’t have to happen overnight. Start with replacing your most worn pieces, keep an eye out for sales, and focus on building a versatile capsule collection that makes you feel amazing inside and out.
Whether you’re crushing it at CrossFit or flowing through a gentle yoga session, you deserve workout clothes that support your health journey, not sabotage it.
